KNOTTER FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 267,972, dated November 21., 1882,

Application filed May 26, 1882.

To all whom it may concern:

Be it.known that I, JOHN EfBUXToN, a citizen of the United States, residing at Owaton-- na, in the county of Steele and State of Minnesota, have invented certain new and useful Improvements in Knotters for Grain-Binders; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompan ying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure l is a side elevation. Fig. 2 is a vertical central section of the knotter proper.

This invention relatesto improvements in knotters for grain-binders and the novelty consists in combining in the bill a cuttingedge and a holding device, all as will now be explained.

In the drawings, A denotes the shank by whichthe knotter is connected with its actnating mechanism, In the lower jaw, G, of the head B is a stationary blade, E, having a knife or'cutting-edge, e, and above it is the hinged cord gripping and holding jaw D, having a heel-extension, d, by means of which, as the shank A is revolved and the said heel-ex? tension is brought in contact with some operatin g device, the jaw will be opened and closed at the proper times. 7

In operation, the cord gripping or holding jaw will serve to detain and hold the twine or cord secure while the process of tyin g the knot is being carried on, and will then release it at the proper moment. The cutting will be done in the. edge e. This cutting-edge is at the front part or end of the blade E. Said blade is so applied or fixed in the lower jaw,

O, of the head that it can readily be fixed in place or removed. This is now indicated by the screw 0, which passes through the lower jaw and the blade.

The device as thus constructed is readily adapted to any ordinary grain-binder, but is more especially designed for such a one as is ModeL) shownin my patent of octoberll, 1881. To the upperpart of the shank any suitable attachment may be made for connecting the knotter with the driving parts of the machine.

The cord is held in the cord-holder in front of the knotter, and when the binder-arm moves back it carries the cord and places it over the knotting-hook. As soon as the packer has gathered the grain into a gavel, and there is sufficient pressure to trip the binder-arm into gear, the cord is brought around the gavel by the binder-arm and over the knotter and to the cord-holder. Then the two cords, or two parts of the cord, are lying together over the knotter, which now revolves, and havingthereby formed the loop at about the completion of one revolution, it receives the said two cords into its open mouth, and the compressing-jaw is now forced down upon the two cords and holdsthem firmly while the loop is pulled off over the points of the knotter. At about the same time the bnndle-discharger, acting on the bundle, pulls the loop offthe knotter and over the bow that has been formed, which bow is caught by the hooked end of the knotter and out by the knife in the end.

Having thus described myinvention, what I consider new, and desire to secure by Letters Patent, is

1. A cord-knotter for grain-binders provided with two rigid jaws, in the end of one of which is fixed a knife or cutting device, and pivoted in the other is a'compressiug or holding jaw having an outwardly-extending heel or tail piece, whereby it is actuated, all substantially as shown and described.

2. In a cord-knotter for grain-binders, the head B, having two rigid jaws, the blade E, provided with cutting-edge c, and the pivoted holding-jaw D, constructed and operating substantially as described.

In testimony whereof I atfix my signature in presence of two witnesses.
